ParsePortRangeToInt parses the port range string and returns start/end ints

func ParsePortSpecs Uses

func ParsePortSpecs(ports []string) (map[Port]struct{}, map[Port][]PortBinding, error)

ParsePortSpecs receives port specs in the format of ip:public:private/proto and parses these in to the internal types

func PartParser Uses

func PartParser(template, data string) (map[string]string, error)

PartParser parses and validates the specified string (data) using the specified template e.g. ip:public:private -> DEPRECATED: do not use, this function may be removed in a future version

func Sort Uses

type PortMap map[Port][]PortBinding

PortMap is a collection of PortBinding indexed by Port

type PortMapping Uses

type PortMapping struct {
    Port    Port
    Binding PortBinding

PortMapping is a data object mapping a Port to a PortBinding

func ParsePortSpec Uses
